Everyone relies on causation all the time. We eat and drink because, among other things, we believe (truly) that not doing so will cause us to die. A climber, Don, takes a rope because he believes (perhaps falsely) that it will cause him to survive if he slips. Bill wants to stop smoking because he believes it may cause him to get cancer, which eventually it does. Invalids take medicine which they believe, truly or falsely, will cause them to recover. Motorists buy petrol because they believe that running out of it will cause their cars to stop. And so on, and so on. And these activities too exemplify causation, all of them being, among other things, caused by our belief in it.
